5.9 TACACS+ Commands
TACACS+ provides access control for networked devices via one or more centralized
servers. Similar to RADIUS, this protocol simplifies authentication by making use of a
single database that can be shared by many clients on a large network. TACACS+ is
based on the TACACS protocol (described in RFC1492) but additionally provides for
separate authentication, authorization, and accounting services. The original protocol
was UDP based with messages passed in clear text over the network; TACACS+ uses
TCP to ensure reliable delivery and a shared key configured on the client and daemon
server to encrypt all messages.
5.9.1 tacacs-server host
Use the tacacs-server host command in Global Configuration mode to configure a
TACACS+ server. This command enters into the TACACS+ configuration mode. The
<ip-address> parameter is the IP address of the TACACS+ server. To specify multiple
hosts, multiple
tacacs-server host
commands can be used.
Format

<ip-address>
Mode Global Config
5.9.1.1 no tacacs-server host
Use the no tacacs-server host command to delete the specified hostname or IP
address. The <ip-address> parameter is the IP address of the TACACS+ server.

5.9.2 tacacs-server key
Use the
tacacs-server key
command to set the authentication and encryption key for
all TACACS+ communications between the switch and the TACACS+ daemon. The
<key-string> parameter has a range of 0 - 128 characters and specifies the
authentication and encryption key for all TACACS communications between the
switch and the TACACS+ server. This key must match the key used on the TACACS+
daemon.

5.9.2.1 no tacacs-server key
Use the
no tacacs-server key

key for all TACACS+ communications between the switch and the TACACS+
